Helper functions for manipulating arrays.

Arr & ArrDots

Arr and ArrDots contains a set of static helper methods for arrays. These methods can be used on both array and \ArrayAccess objects. See the PHPDocs inside the classes for more information.

Dots

Dots is an implementation of \ArrayAccess that uses the functions from \MadeSimple\ArrDots. Instances of Dots can be passed into ArrDots as if it were an array.

There are three ways to create a Dots:

// Create an empty dot array
$dots = new \MadeSimple\Dots();

// Create a dot array with a pre-existing array
$dots = new \MadeSimple\Dots($array);

// Create a dot array with 
$dots = new \MadeSimple\Dots([
    'address' => [
        'houseNo'  => '123',
        'street'   => 'Fake St',
        'postCode' => 'AB12 3CD',
    ],
    'comments' => [
        'Lorem ipsum dolor sit amet, consectetur adipiscing elit.',
        'Donec nec pellentesque est.',
        'Quisque volutpat quam et est laoreet, vitae consectetur erat molestie.',
    ]
]);

Once a Dots is created you can replace the underlining array in the following ways:

// Set an array after dot array
// Changes will _not_ be reflected in the original array
$dots->setArray($array);

// Set an array as a reference
// Changes will be reflected in the original array
$dots->setReference($array);

Basic usage of Dots:

// Get a value using dot notation:
echo "Post Code: ", $dots['address.postCode'], PHP_EOL;

// Set a value using dot notation:
$dots['address.postCode'] = 'EF45 6GH';
echo "Post Code: ", $dots['address.postCode'], PHP_EOL;

// Remove a value using dot notation:
unset($dots['address.postCode']);
echo "Exists: ", (isset($dots['address.postCode']) ? 'yes' : 'no'), PHP_EOL;

// Add a value using dot notation:
$dots['address.postCode'] = 'IJ78 9KL';
echo "Post Code: ", $dots['address.postCode'], PHP_EOL;

// Access nth element in an sub array
echo "Comment: ", $dots['comments.1'], PHP_EOL;
